The video introduces version control systems, emphasizing their importance in collaborative coding. It discusses the challenges of manual code exchange and highlights the benefits of version control, such as tracking changes, facilitating collaboration, and reverting changes. The video explains different types of version control systems: local, centralized, and distributed, with a focus on distributed systems. It concludes with an overview of popular version control systems like Git, Bitbucket, and others.

Why is a version control system essential in collaborative coding projects?

• It prevents any changes from being made to the code.

• It automatically writes code for developers.

• It ensures that only one developer can work on a project at a time.

• It allows developers to work on the same code simultaneously without conflicts.

What is one of the main advantages of using a version control system?

• It prevents any code from being deleted.

• It eliminates the need for code testing.

• It automatically fixes bugs in the code.

• It tracks changes and allows reverting to previous versions.

Which type of version control system is best suited for a single developer?

What is a key feature of a distributed version control system?

• It requires an internet connection at all times.

• It has both a local and a central repository.

• It only works on a single developer's machine.

• It does not allow code sharing.

What happens if the centralized repository is not accessible in a centralized version control system?

• Developers cannot access or modify the code.

• Developers can continue working with their local copies.

• The system automatically switches to a distributed model.

• The code is automatically backed up to a cloud service.
